I opened $SPY VERTICAL 240614 PUT 538.0/PUT 539.0$  ,📊 Fair bit of market makers’ positioning of positive GEX and negative VEX at 540, indicating a moderate zone of support at that level for the coming expiration at 14/6. Slight bias to the upside at least for this expiration term. Here’s a short bull put spread to play on this hypothesis. 🤞
